}

Tests:

build strings and compare them
const s1 = translate(123456, 'foo'.repeat(50)); const s2 = translate(123456, 'foo'.repeat(50)); results1.push(s1 !== s2);
compare declarative objects
const t1 = getTranslatable(123456, 'foo'.repeat(50)); const t2 = getTranslatable(123456, 'foo'.repeat(50)); results2.push(isEqual(t1, t2));
